Check Atmosphere Pressure Using Arduino Mega 2560

Introduction

  • In this article, I will explain about checking the atmospheric pressure by using Arduino Mega 2560.
  • It can correctly give the range of pressure in the serial monitor.
Parts Of List
  • Arduino mega2560
  • MPX4115A
  • Dual power supply
  • LM741
  • Bread Board
  • potentiometer
MPx4115A
  • It can correctly give the air pressure in the atmosphere.
  • It can be a barometer application.

LM741 Operation Amplifier
  • Very common type of OP-AMP, It provides overload production on the input and output
  • It can be easy to use.

Programming
  1. void setup()       
  2. {      
  3.    serial. begin(9600);      
  4. }      
  5. void loop()      
  6. {      
  7.    int sensorvalue = analogread(A0);      
  8.    float voltage = sensorvalue * (5.0 / 1023.0);      
  9.    serial.println(KPa)  
Explanation
  • In this article, I explained about checking the atmosphere temperature in the arduinomega2560
  • It can be connected to the digital meter and displayed in the serial monitor.
